Achilles tendinitis, also known as achilles tendinopathy, is when the Achilles tendon, found at the back of the ankle, becomes irritated. The most common symptoms are pain and swelling around the affected tendon. The pain is typically worse at the start of exercise and decreases thereafter. Stiffness of the ankle may also be present. Onset is generally gradual.

It commonly occurs as a result of overuse such as running. Other risk factors include trauma, a lifestyle that includes little exercise, high-heel shoes, rheumatoid arthritis, and medications of the fluoroquinolone or steroid class. Diagnosis is generally based on symptoms and examination.

While stretching and exercises to strengthen the calf are often recommended for prevention, evidence to support these measures is poor. Treatment typically involves rest, ice, non-steroidal antiinflammatory agents (NSAIDs), and physical therapy. A heel lift or orthotics may also be helpful. In those in who symptoms last more than six months despite other treatments, surgery may be considered. Achilles tendinitis is relatively common.
